GUN SIGHT Filed Sept. 12, 1939 tained within a tube.

Patented Apr. 8, 1941 UNITED ST TES PATENT OFFICE Application 1:59:33? No. 294,530

This invention relates to a 81m sight, and-it is an object of the invention to provide a gun sight wherein the actual sighting mechanisms, such as peeps, crotches, crosshairs, etc., are con- The invention also has for a gun sight of a character which will substantially eliminate light reflection, iuzziness, blur, shadows, glare, etc. resulting from different degrees and variations of light coming from diflerent angles,

Another object of the invention is to provide a gun sight which, when looked through by a shooter, will appear as a single unit and thus enabling the shooter to concentrate only on two things when sighting. viz. the sight and the object being shot at.

A further object of the invention is to provide a gun sight which can be readily mounted on difierent kinds of guns and wherein the sight is so constructed and arranged to allow for refined adjustments for both windage and ele-. vation and thus enable the shooter to do pre ment of the several parts of my improved gun sight whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will herein-i after be definitely claimed.

an object to provide lens-into be varied tosuit an individual-shooter or a particular gun. A supporting unit A is provided for the muzzle end portion of the tube I, said unit being also constructed and arranged to provide for adjustment for windage. A supporting unit Cis' associated with the rear end portion of the sight tube l and this unit C. is also constructed and arranged to provide means to adjust the tube l for elevation.

The top portion of the barrel at a desired in which is held'the intermediate member I of an upstanding U-shaped post P. The side arms 4 of this postEf. as herein disclosed, are straight from end to end and in parallelism and at right angles to the intermediate member 3. As is clearly illustrated in Figure '2, the arms 4 of the 'post P are spaced apart in a direction transunderstood, I will now proceed to describe the same with reference to the accompanying drawing, wherein:

Figure 1 is a view in side elevation with portions broken away of a gun sight constructed in accordance with an embodiment of my invention and in applied position upon a gun barrel;

Figure 3 is an enlarged detailed sectional view taken substantially on the line 3-4 of Figure 1 with parts in elevation. a,

As disclosed in the accompanying drawing, B denotes a conventional barrel of a bolt action type of gun and which is associated in a conventional manner with a general type of stock 8.-

My improved gun sight as herein embodied comprises an elongated sight tube I the inside and 1 outside diameters of which together with its In order that my invention may be thebetter f versely of the barrel B and the upper extremities of the arms 4 are provided'with the openings 5 through which are ireely insertibie the elongated threaded bar 6. The bar 6 is oi a length substantially equal to the-distance betweenfhe outer faces of the arms 4, and "threading, u on the opposite end portions of this bar 6 are the nuts I. These nuts I are round and are sn gly received within the rabbets 8 at. the outer ends of the openin s 5.

The bar 6 is freely disposed through .a collar or sleeve 9 which provides a base for theupstanding spring clamping arms ll. These arms Ill straddle from below the forward or muzzle end portion of the sight tube land are tightly engaged therewith in a conventional manner by the coacting screw ii and nut l2.

The sleeve or collar 9 readily moves or shifts lengthwise oi the bar 6, such movement bein under control of the nuts l4 threaded upon the bar 6. The sleeve or collar 9, asparticularly illustrated in Figure 2 of the drawin is p sitioned between the nuts H which are preferably of a round type. By requisiteturning of the nuts l4 the sleeve or collar 9 may be moved or shifted lengthwise of the bar 6 to efl'ect desired adjustment foi-windage tor the forward or muzzle end of the sight tube 6. Upon obtaining the desired selective adjustment of the sleeve or collar 9 such adjustment is maintained by causing the nuts l4gto have close or tight contact with the ends of the collar or sleeve 8.

The mounting oi the collar or sleeve 9 upon the bar 8 also provides means to provide for the tilting of the tube vI in a plane at right angles to the bar 6.

The upper. surface of the gun barrel B at a desired point inwardly or the groove or channel 2 is provided thereacross with a second transversely disposed groove or channel il in which is snugly engaged a base plate It comprised in the structure of the unit C. Threading into the opposite end portions of this base plate It at n points spaced lengthwise thereof are the lower have these rods I1 spaced laterally with respect to the barrel B.

The rods I! are freely disposed through the openings I8 provided in the opposite end portions of an elongated bar I9. This bar I9 is, of course, above the base plate I and is alsodisposed transversely with respect to the--barre1 B.

Threading upon each of the rods II are the nuts 20, one of which is positioned above the bar I9 and the other therebelow. These nuts 20 are preferably round and have close contact with the adjacent end portion of the bar I9. By requisite rotation of the nuts 20 on the rods II the bar I9 may be readily moved up and down on the rods I1 and rigidly support said bar in desired selected adjustment along the rods I1.

Mounted upon the bar I9 midway of the rods I1 is a clip or spring clamp 2I. This clip or clamp 2I includes a base 22 in direct contact from above with the bar I9 and threading from below through the bar I9 and into the base 22 is a holding or set screw 23. v

The clip or spring clamp 22 is of a type of straddle the tube I from below and said clip or clamp is tightly held in engagement with the tube I in a conventional manner by a tightening screw 24 and associated nut 25. Upon raising or lowering the bar I9 along the upstanding rods II, the rear end portion of the sight tube I is raised or lowered to obtain the desired adjustment of the tube I for elevation. I

The rear end portion of the tube I has inserted therein a rear peep sight insert 26 while within the forward or muzzle end portion of the tube I is av front sight insert 21. This insert 21 preferably comprises a device having sighting elements arranged in the form of a cross. It is to be understood that the front sight insert may be of other types.

' It is also to be particularly pointed out that the inserts 26 and 21 are positioned inwardly of the adjacent ends of the tube I suflicient to substantially free the gun sight from interference due to light reflection, glare, distortion, etc. It is further to be pointed out that the tube I serves effectually to cut oif practically all direct light from striking the actual sighting parts.

It is to be also stated that fair accuracy can be Bbtained by using the tube I without sight inserts and that the farther the inserts 26 and 21 are installed inwardly from the ends of the tube I, the less they will be afiected by lighting.

From the foregoing description it is thought to be obvious that a gun sight constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof andfor this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention'in practice except as hereinafter claimed.

I claim:
